Sony to announce “release plans” for PS4 at Gamescom presser, also Vita update

We previously discussed how Sony would be talking about unannounced games at their press conference in Germany on Tuesday, but hidden away on uk.playstation.com is this tidbit: “We’ll kick off the show at 18:00 BST on 20 August 2013 with a briefing to media on our release plans for PlayStation 4, as well as updates on PlayStation 3 and PlayStation Vita.” So expecting release dates is in fact the thing to do, as we suspected. And could those PS3 and Vita updates involve price drops?
